By sequentially treating the unsaturated carbene IPr [IPr = 1,3‐bis(2,6‐diisopropylphenyl)imidazol‐2‐ylidene] with heavier alkali‐metal alkyls Na R or K R ( R = CH 2 SiMe 3 ) and Ga R 3 , novel heteroleptic gallates 1 and 2 were prepared. Incorporating anionic NHC ligands, these bimetallic complexes react selectively with electrophilles to afford neutral abnormal NHC Ga complexes under mild conditions.
